“…Nectria coccinea sensu lato is an established wound parasite of Fagus sylvatica (PARKER 1975) and of Populus L. spp. (KONING 1938), and has also been associated with dieback of other genera including Acer L. (PEACE 1962).…”

Severe bark necrosis in large Acerpseudoplatanus was studied at a site in northern England. Bark death occurred late in the growing season or in the dormant season on two occasions and was preceded by a notably dry summer in both cases.Of several fungi isolated from cankers and areas of recent bark necrosis, Nectria coccinea and Diplodina acerina were demonstrated to be capable of causing limited necrotic extension of physical wounds in healthy A. pseudoplatanus. A third sp., Phomopsis pustuhta, though the most frequently isolated fungus, showed no such ability.It is proposed that summer drought in association with a variety of weakly pathogenic fungi can induce local bark necrosis in A. pseudoplatanus.

1. Within a seed orchard in southern England, beech trees (Fagus sylvatica L.) belonging to three clones were artificially infested by introducing beech scale larvae (Cryptococcus fagisuga Lind. Hornoptera: Coccidae) into small cages attached t o the bark.2. Some larvae developed t o fecund adults on trees of two susceptible clones but all failed t o develop on a third, resistant clone.3. Within susceptible clones, survival of larvae on individual trees was positively related t o their degree of natural infestation.4. Larvae deriving from several separate trees differed significantly in their ability to survive when inoculated onto trees of susceptible clones. 5. Five forest trees which acted as both donors of larvae and as hosts for artificial inoculation were each inoculated with larvae from all five trees.6. There was significant variation in survival of inoculated larvae both between the host trees and between sources of larvae on each host. 7. Survival of larvae reinoculated onto their original host was significantly higher than that of larvae originating from other trees.8. Fecundity of adults on the forest trees was positively correlated with the probability of inoculated larvae surviving to the adult stage.
